Specification of Letters Patent.

Application filed October 10, 1911.

Patented Apr. 22, 1913.

serial No. 653,796.

To all whom it may concern Be it known that I, HARRY GILLIAM, a citizen of the United States, residing at Springfield, in the county of Clark and State of Uhio, have invented new and useful Improvements in Incubatore, of which the following is a specification.

This invention relates to incubators and the object of the invention is to provide a simple and eflicient device of this character which is constructed to operate without a fire and at the same time to maintain a substantially even temperature throughout the hatching period.

A further object of the invention is the provision of a device of this character wherein the tray support is supported directly by the tank or heatingv element so that the heating element and tray support may be removed from the casing as a unit and where the tray drawer may be removed independently of the tray support.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawing which forms a part of this application, and in which Figure 1 is a perspective view of the device. Fig. 2 is a longitudinal section therethrough. Fig. 3 is a transverse section. Fig. 4 is a perspective view of the tray drawer removed. Fig. 5 is a similar view of the tray. Fig. 6 is a perspective view of the heating element and tray drawer support removed from the casing.

Referring more particularly to the drawing, 1 represents a casing which is supported upon legs 2 and is provided with a removable top 3 which is secured to or otherwise connected to the casing and has a port or opening 4 therein for a purpose which will hereinafter be described. The end 5 of the casing is provided with a sight glass 6 and the end 7 of the casing is provided with an opening 7 through which t-he tray supporting drawer 8 is adapted to pass. Secured in each ycorner of the casing are reinforcing uprights 9 having supporting shoulders 10 formed therein upon which rests the hot water tank 11. This tank has a plurality of substantially U-shaped pipes 12 connected to the bottom adjacent the side edges thereof and extending beneath a drawer supporting frame which consists of a side member 13 and a bottom member 14. The said members are notched as shown at 15 to receive the pipes 12 and project slightly beyond the .bottom which rests directly upon the pipes as shown. The frame is somewhat narrower than the tank so that the side pieces will lie inside of the pipes 12 so as to provide a space 1G which is filled with any suitable heat insulating material such as mineral wool or the like. This space extends the full depth of the casing on the sides thereof and the depth of the tank on the 'ends thereof, the insulation being lifted out in front of the sight glass at the opening 7. The space also extends over the top of the tank, between the same and the top of the casing.

Projecting vertically from one end of the tank and passing through the opening 4 in the top is a supply pipe 17 which is provided with a valve 18 and'with a funnel 19. Adjacent the opposite corner of the tank, an outlet nipple 20 is secured tp the tank and passes through an aperture 21 in the casing and is provided with a valve 22 to control the discharge of the liquid from the tank.

A suitable tray receiving drawer 23 is slidably mounted in the casing and rests upon the bottom 14 of the support-ing frame and is provided with a sight glass 24 in its front-'end so that the contents of the tray 25 may be properly inspected from the front end of the machine. lVhen the drawer and this tray are removed from the casing and frame and the top 3 is removed from the casing, the tank and this supporting frame may be removed from the casing as a unit.

The bottom 26 of the casing 1 is provided with a plurality of vent holes 27 which are covered by shields 28 and the bottom 14 of the frame is also provided with vent holes 28 so that the eggs may be properly ventilated during incubation.

In the operation of this device a sufcient quantity of water to fill the tank is broughtto the boiling point and placed in the tank so as to heat the same and radiate the heat thereof over the eggs. This heat from the hot water will last approximately twelve hours when it is renewed by withdrawing a small portion of the water and again heating it to the boiling point and inserting it in the tank with the partially cool water. It has been found by actual demonstration that this method of incubation' is much more satisfactory than that of a thermostat regulator. At the latter part of each heating period, the water in the tank has its temperature sufliciently reduced to properly cool fthe eggs so that they will never become over- In an incubator, a casing, a hot water tank' removably mounted therein, radiating pipes depending from the tank, a drawer supporting frame carried by said pipes and comprlsing side and bottom members, said side members being provided with notches to receive and hold the pipes in spaced relation,

and a tray supporting drawer mounted i1 the frame and projecting through the casing, said drawer locking the tank against removal when in posit-ion in the frame.

In testimony whereof I affix my signature in presence of two witnesses.

HARRY GILL'IAM.
